If you really want a clean flame cut you will need to chuck the beaker in a lathe so it is turning. You could otherwise use some rollers to keep it steady in the flame. A thin hot flame is what your gonna need to cut it and have a punty attached to the bottom middle so you have a handle to pull the bottom away with when it gets hot enough all the way around. The punty will also allow you to spin it without having to hold that big beaker top in your fingers and try to spin that. And for sure anneal it first.
